I have a room that is 1440 cubic feet. I am using a C.A.P co2 generator keeping the room constant at 1500ppm and because it produces heat, my temp goes up to about 89-92 degrees. I am currently in veg and I leave the co2 on for 12 hours of my light cycle and turn it off for the other 6 hours which happen to be the hottest part of the day. The temps in the room are: 85-92 for the first 12 hours when the co2 is on 75-80 for the remaining 6 hours of the light cycle 68-73 during the 6 hours of darkness My questions are as follows: 1) What temp should the room be when using co2? 2) Is there a problem with running it 12 hours out of the 18 hour veg cycle? 3)Is there any potential problem with my temperatures?
